Romanian prosecutors have launched a criminal investigation against a far-right populist who won the first round in a canceled presidential election last year.

Romanian lawmakers have voted narrowly in favor of a new pro-European coalition government led by incumbent Prime Minister Marcel Ciolacu.

Romania’s leftist Social Democratic Party has withdrawn from negotiations to form a pro-European coalition government, extending political turmoil that has gripped the European Union country after a top court annulled a presidential election.

Electoral data shows a far-right populist leads in Romania’s presidential election and will likely face leftist Prime Minister Marcel Ciolacu in a runoff in two weeks.
